With „high-low” clamping
For easily deformed components SMW-AUTOBLOK offers ”high-low“ clamping. The gripping force of the chuck can be reduced from a large amount of gripping force used in roughing, to a smaller amount of gripping force for a finishing cut.
The combination between the SIN-HL cylinder and a SMW-AUTOBLOK ”high-low“ suitable chuck allows a monitored reduction in the gripping force. The component remains clamped in the chuck safely, however, the stress of the component can be released.
The result are round components with a minimum of deformation. The ”high-low“ cycle is programmable and is finished completely within 2-4 sec. For additional information please ask our engineers.
